Ball joints are essential components of a vehicle’s suspension system, acting as pivot points between the control arms and the steering knuckles. They allow for smooth movement of the wheels during steering and suspension travel, enabling the wheels to move up and down while also turning. Ball joints are designed to withstand high loads and friction and they are often equipped with a grease fitting or sealed unit to maintain lubrication. Over time, ball joints can wear out due to stress, dirt or lack of lubrication, leading to symptoms like clunking noises, steering instability or uneven tire wear. Replacing worn ball joints is crucial for maintaining safe handling, steering control, and overall suspension performance.
